The other text field contains the binary number which should be written to the digital I/O lines 0-6. Virtual LEDs show the state of these lines. The seven-segment display is connected to digital I/O lines 8-14 and segments are turned on/off according to the state of these pins. The lower part contains a slider ranging from 0 to 9 (control), two text fields (indicator), 7 virtual LEDs, and a seven-segment display.
